The Highway Automotive 10106009 is a panel radiator (reference CP2026) designed as a direct replacement for Caterpillar D5 construction equipment. Built to restore cooling system performance in demanding site conditions, this unit is engineered to match original-equipment standards for the application.
Constructed from S/B (soldered brass) material, this panel radiator offers reliable thermal performance suited to heavy construction plant. The panel format and precise material specification ensure compatibility with the cooling circuit demands typical of Caterpillar D5 machines.
The radiator measures 838 mm high by 165 mm wide by 26 mm deep, providing an exact dimensional reference for installation verification. The single-application fitment for the Caterpillar D5 means this unit is purpose-matched rather than a broad-fit substitute, giving workshop technicians confidence in specifying the correct replacement.
This replacement is cross-referenced against OE part number 4W4146, allowing straightforward identification against existing service records and parts documentation. Workshop teams sourcing the unit against the original OE reference can confirm equivalence directly from this cross-reference data.
